The invention provides an improved warp knitting method. The knitting method is characterized in that a guide bar GB1 performs yarn laying and loop forming on a front needle bed and a rear needle bed and performs knitting as a common guide bar of the front needle bed and the rear needle bed; a guide bar GB2 performs yarn laying and loop forming on the front needle bed and the rear needle bed and performs knitting as a common guide bar of the front needle bed and the rear needle bed; a guide bar GB3 performs yarn laying and loop forming on the front needle bed and the rear needle bed and performs knitting as a common guide bar of the front needle bed and the rear needle bed; a guide bar GB4 performs yarn laying and loop forming on the front needle bed and the rear needle bed and performs knitting as a common guide bar of the front needle bed and the rear needle bed; a guide bar GB5 performs yarn laying and loop forming on the rear needle bed and performs knitting on the rear needle bed; a guide bar GB6 performs yarn laying and loop forming on the rear needle bed and performs knitting on the rear needle bed. The guide bars GB1, GB2, GB3 and GB4 perform knitting as the common guide bars of the front needle bed and the rear needle bed; the guide bars GB5 and GB6 perform knitting on the rear needle bed; the six guide bars cooperate to knit warp knitting fabric which achieves a strong three-dimensional effect and has a unique overall style, thus being difficult to imitate.
